Z Claims.

The present invention pertains to a novel straw bruiser or a device forcutting or bruising such material as straw While it is being dischargedfrom a threshing machine by means of a blower.

The invention consists in fact in a modification of the blower structureapplied to the threshing machine. The blower consists of a housing inwhich is mounted a bladed rotor for throwing the material through thedischarge pipe. According to the invention, cutting blades are attachedto the rotor in such a manner as to be spaced slightly from certainedges of the cutting blades.

A set of knives is suitably secured to the xed rotor housing.Preferably, the lateral inlet of the housing is formed with an inwardlyextending flange, and the knives are secured in spaced relation to theflange. The `knives are s disposed that they are received in the spacebetween the cutting blades and the rotorv blade edges when the rotor isin motion. Consequently the knives attack the material eiectively andcooperate with the cutting blades in the manner of shears. The material,after having been thus treated, is discharged from the housing by theaction of the rotor.

The invention is fully disclosed by way of example in the followingdescription and in the accompanying drawing in which:

Figure 1 is a side elevation of the device with the chute removed;

Figure 2 is an elevation of the rotor;

Figure 3 is a vertical diametrical section of the blower housing,showing the rotor in elevation, and

Figure 4 is a side elevation of the apparatus applied to a threshingmachine.

Reference to these views will now be made by use of like characterswhich are employed to designate corresponding parts throughout.

In Figure 4 the numeral I designates the rear end of a threshing machinewhich may be of usual construction. The machine is adapted to throwmaterial such as straw into a chute 2 which communicates with a blowerhousing 3, which has an adjustable vdischarge pipe 4 for delivering thematerial to a desired location. As shown in Figures l and 3, one side ofthe housing 3 has open side 5 to provide communication with the chute2'.

In the center of the housing 3 is journalled a shaft driven from themechanism of the threshing machine in any suitable manner. Within thehousing, the shaft carries a square hub or block 1 to the sides of whichare fastened outwardly extending spokes 8, as shown more clearly inFigures 1 and 2. To the spokes in turn are attached paddles or blades 9extending substantially to the periphery of the housing 3. Each blade 9has an inclined edge Ill crossing its spoke B, as may be seen in Figure2, for a purpose that will presently be described.

Inward of each edge I0, the corresponding spoke 8 is formed with alaterally extending flange I I to which is attached a cutting blade I2.The blades I2 extend parallel to the corresponding edges I Il and areslightly spaced therefrom as may be seen in Figures 2 and 3. Y

Around the opening 5, the housing 3 is formed with an inwardly extendingangular flange I3 to which are attached a number of spaced knives I4.These are obviously stationary and are so disposed as to be received inthe spaces between the rotary blades I2 and the corresponding edges I0when the latter are in rotation, as may be seen in Figure 3.

In the operation of the device, the material such as straw that entersthe housing 3 from the chute 2 is whirled by means of the rotatingpaddles. 9. As the material strikes the fixed knives I4, the cuttingblades I2 cooperate with the knives in the manner of shears. In thismanner the material is cut or bruised and is eventually dischargedthrough the pipe 4.

Although a specific embodiment of the invention has lbeen illustratedand described, it will be understood that various alterations in thedetails of construction may be made without `departing from the scope ofthe invention as indicated by the appended claims.

What I claim is:

1. A straw bruiser comprising a housing, means for feeding materialthereto, a rotor in said housing, whirling paddles and cutting bladescarried by said rotor, said blades being spaced respectively from saidpaddles axially with respect to said rotor, and a plurality of knivesxed to said housing and adapted to be received in said spaces onrotation of said rotor, whereby to cooperate with said cutting blades.

2. A straw bruiser comprising a housing having an inlet opening in aside wall thereof, a rotor in said housing, whirling paddles carried bysaid rotor and having each an annular edge, cutting blades carried bysaid rotor and extending parallel to said angular edges and formingspaces therewith, and a plurality of knives iixed to said housing andadapted to be received in saidV spaces on rotation of said rotor,whereby to cooperate with said cutting blades.
